German poet Johann Wolfgang von Goethe writes The Morphology of Plants stating that all plant organs, flowers included, began as leaves — an assertion that will enjoy some support from 21st-century genetic research.

Luigi Galvani announces that electricity applied to severed frog's legs causes them to twitch and that frogs legs twitch in the presence of two different metals with no electric current present. The latter discovery eventually leads to Alessandro Volta's developing the electric battery.

Pierre Prévost develops his theory of exchanges of radiation of heat. He correctly shows that cold is merely the absence of heat and that all bodies continually radiate heat. If they seem not to radiate heat, it means that they are in heat equilibrium with their environment.

Reverend James Douglas publishes Nenia Britannica; or, A Sepulchral History of Great Britain providing perhaps the first record of a fossil (sea urchin) at an archaeological site.

John Frere describes and illustrates handaxes from Hoxne that will turn out to be some 400,000 years old.

Erasmus Darwin (Charles' grandfather) publishes Zoonomia, or the Laws of Organic Life.

James Hutton publishes An Investigation of the Principles of Knowledge. Buried in the 2,138-page philosophical tome is a chapter about variety in nature in which Hutton anticipates Charles Darwin's theory of natural selection.

John Dalton's Extraordinary facts relating to the vision of colors gives an early account of red-green color blindness, which he refers to as Daltonism, since he is afflicted with the condition.

Zoonomia, or the Laws of Organic Life by Erasmus Darwin (grandfather of Charles Darwin) contains his ideas about evolution, which are Lamarckian in that they assume the environment has a direct influence on organisms, causing permanent changes in the germ line.

Alessandro Volta demonstrates that the electric force observed by Galvani is not connected with living creatures, but can be obtained whenever two different metals are placed in a conducting fluid.

Alessandro Volta demonstrates that the electric force observed by Galvani is not connected with living creatures, but can be obtained whenever two different metals are placed in a conducting fluid.

Johann Friedrich Blumenbach publishes De generis humani varietate nativa liber arguing that humans comprise a single species with five varieties: Caucasian, Mongolian, Ethiopian, (American) Indian and Malayan.

James Hutton overturns the "Neptunian" view of rock formation in his Theory of the Earth, suggesting instead that forces of rock creation are balanced by forces of rock destruction.

Henry Cavendish determines the mass of Earth by measuring the gravity between two small masses and two large masses. This gives the gravitational constant G, which was the only unknown in Newton's equations. Solving for G enables Cavendish to establish that Earth is about 5.5 times as dense as water.

Enquiry concerning the source of heat which is excited by friction by Count Rumford (Benjamin Thompson) describes his experiments with boring cannons that show that the caloric theory of heat cannot be true, and that heat should be considered a kind of motion.

The first mammoth fossil fully documented by modern science is discovered near the delta of the Lena River in 1799 by Ossip Schumachov, a Siberian hunter. Schumachov allows it to thaw (a process taking several years) until he can retrieve the tusks for sale to the ivory trade in Yakutsk. He then abandons the specimen, allowing it to decay before its recovery. In 1806, Russian botanist Mikhail Adams rescues what remained of the specimen and brought it to the Zoological Museum of the Zoological Institute of the Russian Academy of Sciences in St. Petersburg. The specimen, which became known as the Adams Mammoth, is stuffed and mounted, and continues to be on display at the Zoological Institute.

Charles White publishes An Account of the Regular Gradation in Man, and in Different Animals and Vegetables, a treatise on the great chain of being, showing people of color at the bottom of the human chain.

Faujas publishes a description of the Maastricht animal, a spectacular mosasaur found in chalk quarries in the Netherlands, describing it as a crocodile.

Thomas Jefferson publishes a paper describing Megalonyx, a North American fossil ground sloth similar to the one found in South America.

George Shaw publishes a description of a platypus even though he suspects the odd animal might be a hoax.

Alexander von Humboldt names the Jurassic System, after the Jura Mountains. This time period will later be identified as the "middle period" for the dinosaurs.

William Smith maps rock formations in the vicinity of Bath, England, making perhaps the world's first geologic map. The same year, Smith, Joseph Townsend and Benjamin Richardson recognize rocks containing the Permian and Triassic, though not necessarily by those names. (These periods will later be identified as spanning the Earth's most catastrophic mass extinction.)

The British government purchases the collection of Scottish anatomist John Hunter, forming the Hunterian Museum.

ESP Quick Facts

ESP Origins

In the early 1990's,
Robert Robbins
was a faculty member at Johns
Hopkins, where he directed the informatics core of GDB
— the human gene-mapping database of the international human
genome project. To share papers with colleagues around the world, he
set up a small paper-sharing section on his personal web page. This
small project evolved into The Electronic Scholarly
Publishing Project.

ESP Support

In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research
Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured
funding, through the ELSI component of the US Human Genome Project, to
create the original ESP.ORG web site, with the formal goal of
providing free, world-wide access to the literature of classical genetics.

ESP Rationale

Although the methods of molecular biology can seem almost
magical to the uninitiated, the original
techniques of classical genetics are readily appreciated by one and
all: cross individuals that differ in some inherited trait, collect
all of the progeny, score their attributes, and propose mechanisms
to explain the patterns of inheritance observed.

ESP Goal

In reading the early works of classical genetics, one is drawn, almost
inexorably, into ever more complex models, until molecular explanations
begin to seem both necessary and natural. At that point, the tools
for understanding genome research are at hand. Assisting readers reach
this point was the original goal of The Electronic Scholarly Publishing
Project.

ESP Usage

Usage of the site grew rapidly and has remained high. Faculty began
to use the site for their assigned readings. Other on-line
publishers, ranging from The New York Times to Nature
referenced ESP materials in their own publications. Nobel laureates
(e.g., Joshua Lederberg) regularly used the
site and even wrote to suggest changes and improvements.

ESP Content

When the site began, no journals
were making their early content available in
digital format. As a result, ESP was obliged to digitize classic
literature before it could be made available. For many important
papers — such as
Mendel's original paper
or the
first genetic map
— ESP had to produce entirely new typeset versions of the works,
if they were to be available in a high-quality format.

ESP Help

Early support from the DOE component of the Human Genome Project was
critically important for getting the ESP project on a firm foundation.
Since that funding ended (nearly 20 years ago), the project has been
operated as a purely volunteer effort.
Anyone wishing to assist in these efforts should send an
email to Robbins.
